MACHINE FOR GRINDING- APPLIES.

Specification of Letters Patent No. 26,892, dated January 24, 1860.

To all whom t may concern:

Be it known that I, IsAAo T. CARPENTER, of Martins Ferry, in the county of Belmont and State of Ohio, have invented a new and useful Machine for Grinding and Pressing Apples and Grapes and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specilication, in which- Figure l, is a general perspective view; and Fig. 2 is a top section exhibiting the arrangement of the grinding rollers, propelling gearing, etc.

The different representationsA of like parts are marked in each gure by identical letters.

A, is the frame of the machine.

B, is the hopper.

C C are two wooden cylinders, the peripheries of which are covered with a grinding surface, consisting of a perforated metallic sheeting or geater a a.

D D D D, are cog-wheels employed to impart the required motions to the grinding cylinders.

The crib, E, receives the pomice from the cylinders.

F, is a screw and lever press.

G, is a box or guard, attached to the hopper B, and placed over the cog wheels D D D D, to prevent accidents.

L is a balance wheel, to equalize the motion of the machine.

The construction of the frame A, hopper B, and guard box G, crib E, screw press F, etc., will be understood by an inspection of the drawings, Figs. l and 2.

The grinding cylinders, Fig. 2, C C', as a matter of economy and convenience, are made of wood, and are covered with a thin metallic sheeting a a; this sheeting is punched with a great number of small holes, the rough and ragged projections of which constitute the grinding surface of the cylinders C C. These cylinders are provided with iron shafts, the journals of which run in the bearings b c ZJ 6. The bearings b 6 of cylinder C are fixed,

while those of b, Z2 of cylinder C, are furnished with a slot c c', for the purpose of placing the cylinders a greater or lesser distance apart-an expedient employed to prevent the chilling of the grinding surface by attrition upon each other, to which they are liable in consequence of the cylinders becoming wet, and swellin when used for any considerable length o time.

To grind apples the cylinders C C are made to revolve with different velocities, one moving considerably faster than the other, so as to mash and also tear the apples as much as possible. This motion is obtained by using the pinion and driver D, D, the wheel D being either removed or permitted to turn freely on its axis. In grinding grapes, I give the cylinders the same velocity, in order to mash, but not tear the pulp; this motion is obtained by removing the pinion D, and keying fast the wheel D.

l'Ihe machine is operated by applying power to the shaft of roller C, which may be by means of crank H, or otherwise. The fruit being placed in the hopper B, is operated upon by the grinding surfaces of cylinders C, C the pomice being discharged into crib E. When full the crib E is passed along the bottom I, and placed under the screw press F. The head J is then placed in the crib E, and the power of press F is brought to bear upon the pomice, the liquid being forced through the openings in the crib, E, upon the bottom I whence it is discharged throuofh the spout K into a receiving vessel. After being thoroughly pressed by press F, the residuum is removed, and the crib E replaced beneath the cylinder C C', to be again filled and operated upon as before. To facilitate the work two cribs may be used, the one being' filled while the other is being pressed and vice versa.

I do not claim broadly the application of two cylinders, revolving with either equal or different velocities, as I am aware that this feature is not novel; neither do I claim grinding cylinders, sheeted or otherwise, when said cylinders are furnished with a grinding surface consisting of ribs, spikes, nails or their equivalents.

What I claim as my invention, and desire constitute the grinding surface of cylinders to secure by Letters Patent is: C C.
